Cooling device for cooling at least one electric line which is connected to a plug connector part

Abstract

A cooling device for cooling at least one electric line which is connected to a plug connector part includes: a cooling module disposable on the at least one electric line and having a cooling channel for flowing coolant therethrough, the cooling module having two housing assemblies, each of which has a respective connection section and a flow opening molded onto the connection section, the two housing assemblies being separate in a preassembly state and being connectable together to be placed on the at least one electric line such that the at least one electric line is received between the housing assemblies. The flow openings of the connection sections of the two housing assemblies are fluidically connected together to form the cooling channel.

1 . A cooling device for cooling at least one electric line which is connected to a plug connector part having comprising:
 a cooling module disposable on the at least one electric line and having a cooling channel for flowing coolant therethrough, the cooling module having two housing assemblies, each of which has a respective connection section and a flow opening molded onto the connection section, the two housing assemblies being separate in a preassembly state and being connectable together to be placed on the at least one electric line such that the at least one electric line is received between the housing assemblies,   wherein the flow openings of the connection sections of the two housing assemblies are fluidically connected together to form the cooling channel.   
     
     
         2 . The cooling device of  claim 1 , wherein each housing assembly has at least one cooling channel portion for forming the cooling channel. 
     
     
         3 . The cooling device of  claim 2 , wherein the at least one cooling channel portion of one housing assembly of the two housing assemblies is fluidically connected to the at least one cooling channel portion of an other housing assembly of the two housing assemblies when the two housing assemblies are connected to one another. 
     
     
         4 . The cooling device of  claim 2 , wherein at least one housing assembly of the two housing assemblies has a body element and a cover element connected to the body element, the body element defining a flow space in which the at least one cooling channel portion extends. 
     
     
         5 . The cooling device of  claim 4 , wherein the cover element has a surface portion defining the flow space and at least one wall portion formed on the surface portion for defining the at least one cooling channel portion. 
     
     
         6 . The cooling device of  claim 5 , wherein the at least one wall portion extends towards the connection section of the at least one housing assembly such that the at least one wall portion divides the flow opening into multiple channel openings. 
     
     
         7 . The cooling device of  claim 5 , wherein the cover element has a plurality of wall portions between which cooling channel portions are formed. 
     
     
         8 . The cooling device of  claim 5 , wherein at least one flow element protruding into the at least one cooling channel portion is formed on the surface portion. 
     
     
         9 . The cooling device of  claim 1 , wherein the cooling module has a sealing element arranged between the connection sections of the two housing assemblies. 
     
     
         10 . The cooling device of  claim 9 , wherein the sealing element has a plurality of sealing webs that separate channel openings associated with different cooling channel portions from one another. 
     
     
         11 . The cooling device of  claim 1 , wherein at least one housing assembly of the two housing assemblies has a receiving groove configured to receive the at least one electric line. 
     
     
         12 . The cooling device of  claim 11 , wherein the cooling channel is shaped such that coolant guided in the cooling channel flows around a boundary portion of the at least one housing assembly that forms the receiving groove. 
     
     
         13 . The cooling device of  claim 1 , wherein the cooling module has at least one connection element for connecting a cooling line. 
     
     
         14 . A plug connector assembly, comprising:
 a plug connector part;   at least one electric line connected to the plug connector part; and   the cooling device of  claim 1  for cooling the at least one electric line.   
     
     
         15 . A charging system for charging an electric vehicle, comprising:
 the plug connector assembly of  claim 14 .
